Marcus's situation
Marcus Johnson is 38, a senior territory manager for a top-10 pharmaceutical manufacturer covering the southeast region. His 2026 W-2: $185K base + $135K commission + $60K bonuses = $380K total. He's on the road Monday-Thursday most weeks, visiting medical practices and hospitals across Georgia, Alabama, and Tennessee. Total travel: roughly 60-65% of working days. Home base: a suburb of Atlanta.
Marcus's wife Diane is a part-time consultant ($55K). Joint AGI lands at $415K — top of the 32% federal bracket, with Georgia state at 5.39%. His CPA mentioned cost segregation last year. Marcus pushed back: "I'm gone half the year — how can I qualify for material participation?" The CPA's response: "If the property is in Atlanta and Diane logs her share, the math works. Out-of-state vacation properties don't."
The proximity rule for traveling professionals
Material participation under IRC §469(h) requires hours spent on the activity. For a pharma rep who's gone 4 days a week, the realistic windows for STR work are:
- Friday-Sunday at home. 3 days × ~2 hours of property work = 6 hours/week × 50 weeks = ~300 hours/year. Plenty.
- Monday morning before travel. ~30 minutes/week × 50 = ~25 hours.
- Phone time during travel days. Bookings, vendor calls, marketing — easily 1-2 hours/week from hotels = ~50-100 hours.
Total realistic hours: 350-400 per year. The 100-hour threshold is achievable comfortably IF the work is doable from home. Doable from home means: Atlanta. Not Aspen. Not Lake Tahoe. Not Bay Area.
For a Tahoe property (3-hour flight), Marcus's available time per visit is consumed by travel. He'd realistically log 30-40 hours/year on the property — not enough. For an Atlanta property, the same calendar produces 350+ hours.
The commission-income wrinkle
Marcus's W-2 income is variable: 2025 was $345K, 2026 projected $380K, 2027 could be anywhere from $310-450K depending on territory performance. This volatility doesn't change the cost-seg math but does change the timing strategy:
- Big-bonus years. Same play as the tech engineer — time the cost-seg study to land on the high-income year if you have flexibility on when to commission it.
- Below-target years. Don't over-commission. A cost-seg deduction that exceeds your W-2 + spouse income becomes an NOL — useful eventually, but not current cash.
- Forecasting accuracy. Pharma reps usually have visibility into their compensation by Q3. Use that signal to decide whether to commission the study in the current year or defer to next year.

Hours documentation for travel-heavy W-2
The audit risk for Marcus is identical to the surgeon's: if the IRS questions material participation, can he prove 350 hours? Three documentation patterns work for traveling pros:
1. Booking-system audit logs
Airbnb, VRBO, and most booking platforms keep timestamped logs of host activity — message responses, listing edits, calendar changes. These logs are admissible in audit and don't require manual reconstruction. Marcus exports his quarterly host activity reports.
2. Time-blocked Google Calendar
Every Friday and Sunday morning, Marcus blocks 1-2 hours of "STR work" on his calendar. He fills in what he did (reviewed bookings, contacted cleaner, ordered supplies, etc.) the same day. Real-time entries that survive Tax Court scrutiny.
3. Vendor email trail
Most STR work generates email — confirmations to cleaners, coordination with handymen, supply purchase confirmations. Marcus keeps a dedicated email folder ("STR-OPS") with every property-related thread. Date-stamped, third-party-confirmable.
The decision tree
When this fails
- Out-of-state vacation property. Tahoe/Aspen/Maui properties for travel-heavy professionals don't survive the hours test. The strategy works for surgeons (who have weekends home) better than reps (who are gone weekends sometimes too).
- Spouse doesn't help. If Diane (Marcus's wife) doesn't materially participate, all hours fall on Marcus, who's gone 4 days a week. Hours threshold gets tight.
- Below-target year. Commissioning the study in a $300K W-2 year instead of $400K creates ~$10K less savings. Time it to the strong years.
- Property under $400K. Atlanta's lower price points exist; below $400K basis the math gets tight.
What Marcus should actually do
Stay local on the STR. Atlanta works (Buckhead, East Atlanta, Decatur are all viable STR markets). Order the study mid-2026 once his commission visibility is clear. Document hours with booking-system exports, Google Calendar blocks, and the dedicated email folder. Hand the study to his CPA before April 2027.
